Abstract (en)

Digital counter register stages RCRG(N) are constructed as two-to-one mux registers, each employing a multiplexer stage (113) having first, second, and third inputs (S0, I0, I1) and an output (116) connected to the switching signal input (D) of a D-type flip-flop (15), whose Q output comprises a first input (I1) to the multiplexer stage (113). An inverter buffer (19) is associated with each register stage (RCRG(N)) and has an input connected to the output (Q) of said D-type flip-flop (115) and an output connected to the second input (I0) of the multiplexer stage (RCRG(N)) and fed forward to a NOR gate (21) associated with each subsequent register stage (RCRG(N)). <IMAGE>
